• getExplosion/setExplosion

  public int getExplosion() / public void setExplosion(int value)
  

• hasDataLabels/hasDataLabels

  public boolean hasDataLabels() / public void hasDataLabels(boolean value)
  

  Gets or sets a flag indicating whether data labels are displayed for the series.

• getInvertIfNegative/setInvertIfNegative

  public boolean getInvertIfNegative() / public void setInvertIfNegative(boolean value)
